If people saw these videos, they would definitely pay more attention to contact with others. Any virus is transmitted through droplets of saliva that we emit when we speak, cough, sneeze. This also applies to covid-19. In my country in open places where there are no gatherings we can remain without a mask but in closed public places it is mandatory. Of course, there is less chance of getting infected outdoors if you respect the distance with people you don't know each other. I hope scientists will find a solution for coronavirus soon. Thanks for sharing these really interesting videos.😊👍
